I've been looking at the Snap Circuit sets for several years now and finally purchased the SC-750 for my daughters 9th birthday. I was a bit worried she was too young for it but found that was not the case. She's already built the voice recorder, FM radio and doorbell projects and had a blast playing with each of them. The projects are really simple to build (I only helped with the first one) by following the detailed instructions and well marked components. She came home yesterday, did her homework and went right to Snap Circuits and began building another project (much better than watching the TV). I look forward to using the computer interface so we can actually learn (together) about electronics. I suspect this is one of those rare toys that that will not gather dust on the shelf.
